1
Pull-ups are generally only enabled on pins with their primary function, except as noted.
2
Refers to pin’s primary function.
3
Enabled only in oscillator bypass mode (internal crystal oscillator is disabled).
4
GPIO functionality is determined by the edge port module. The GPIO module is only responsible for assigning the alternate functions.
5
Pull-up when DREQ controls the pin.
6
The 176 LQFP device only supports a 12-bit LCD data bus.
7
DSPI or SBF signal functionality is controlled by RESET. When asserted, these pins are configured for serial boot; when negated, the
pins are configured for DSPI.
8
Pull-up when the serial boot facility (SBF) controls the pin.
